Ovicellate and two non-ovicellate zooids; ovicellate zooids with labiate flanges proximal and distal to orifice. D. Central region of colony, with ovicellate and non-ovicellate zooids in basal layer and numerous frontal dwarf zooids; arrowhead, dwarf zooid budding from frontal pore chamber. E. Frontal dwarfs; note variation in ooecial pseudopores and in frontal shield; arrowhead, compact frontal shield with tapering costae and sutures evident between costae; arrow, reticulate frontal shield.
